gs-aladdin and Japanese fonts

I'm using debian-testing.
When I handle a ps file including Japanese fonts gs-aladdin doesn't handle
Japanese characters. English characters are fine. It always complain
whenever it finds Japanese characters:
--
Can't find (or can't open) font file /Resource/Font/Ryumin-Light-EUC-H.
Can't find (or can't open) font file Ryumin-Light-EUC-H.
Substituting font Courier for Ryumin-Light-EUC-H
--Substituting font Courier for Ryumin-Light-EUC-H
again and again. And as a matter of course small rectangles appear in the
places of Japanese characters. What's the solution?
I've been using Linux (first redhat, then debian) for more than 6 years, but
I am not an expert of ghostscript, especially handling Japanese (though I'm
Japanese :) .) I guess I should just install appropriate Japanese fonts,
but I'm not sure which one I should install and where. At least I cannot
find among debian packages. So will anyone point me to the appropriate
direction?
The reason why I don't use the standard gs package is that gs package
doesn't handle ps files from mozilla, and cannot print mozilla output.
Fortunately gs-aladdin can handle mozilla output in English. But I want
Japanese also. This is my situation.
Any help I can get would be greatly appreciated.
